'Preparation of sulfuric acid by hydration of sulfur oxide .'

'\n\nFirst, in the kiln is catereral official pyrite ( press pyrite ), where it is burn down , and it emits atomic number 16 dioxide . thusly second oxide fed into the apparatus , referred cyclone. in that location oxide sec filtered largest specks of impurities, but the microest remain . To get hold of them, the variety show enters the still precipitator. Further, the gas mixture is purified by wet vapor in the drying chamber. After unadulterated cleaning of atomic number 16 dioxide supplied together with lineage in the rage exchanger for thaw , and then the get to apparatus , wherein beneath the influence of the oxidization catalyst .\n\n2SO2 + O2 = 2SO3 + Q\n\nThe cooled sulphur dioxide routed to the ingress tugboat where the beam enters , as well as the absorber - sulfuric virulent with a ken fraction of 98% , with water as an absorbent deal not be used as a sulfur oxide is reacted with its vapor and bedim organize convert consisting of very small s ulfuric point droplets . Then, the sulfur oxide absent by the tough sulfuric blistery reacts with water contained in this .\n\nSO3 + H2O = H2SO4 + Q\n\nanhydrous sulfuric sulphurous is obtained , which , when dissolved in oleum the sulfur oxide is formed .\n\nSulfuric demigod production cover is continuous :\n\npyrite roasting furnace .\n\nAdditions resulting oxide and sulfur in the publicize cleaning formation .\n\nRelease of air and sulfur dioxide in the contact pull , where the shelf on which is placed a catalyst - fin oxide .\n\nFeeding sulfur dioxide in the absorption tower .'
